Last morning I had to get up extremely early in my terms – actually that is 8 am, but for someone who worked late shift for the last 7 years it feels like going to work at 3am. Anyway, this gave me a chance to bid on that 8:30 oddball auction and I got this Cisco SFS 3504 allright! A 12-port infiniband switch with 6 gigabit ethernet “downlinks”, incredible 240Gbps switching bandwidth for EUR 35.
It’s a precedessor of the current Nexus-series and got EOL’d in 2008 just one year after its 2007 introduction. This happened along with all other infiniband products by Cisco cleary in a move to unite all datacenter type offerings around the Nexus switches, intending to completely wipe away the infiniband market with datacenter ethernet.
While I wish Cisco all the best on this move and think the idea of reliable Ethernet is thrilling, I certainly couldn’t care less now.
Used twoport Infiniband HCAs run about $40 in the US, and putting the Buzz aside there is a simple fact: 20gbps for approx $45/port is a bit more intriguing than looking at 10gpbs with $600 per HBA and insanely expensive 10GE switches; especially since RMDA support and such are completely new concepts to the ethernet world.
If only I could get my hands on one of the fibrechannel options.
